Description

TECHNICAL FIELD

[0001] The present application relates to the outer ring grinding machine related technical field, specifically to a cylindrical workpiece outer circle grinding machine with active feeding and discharging function. BACKGROUND

[0002] The current cylindrical grinding machine generally relies on manual or mechanical hand devices for feeding and discharging operation when machining shafts, sleeves and other cylindrical workpieces. Although the existing automatic solution can partially replace manual operation, such as the feeding and discharging automatic conveying device for cylindrical grinding machine in CN212286944U, which includes a horizontal guide rail module, a vertical guide rail module and a steering clamping mechanical hand, as well as a feeding conveyor belt and a discharging conveyor belt installed side by side on the stock bin frame, realizing automatic machining and feeding and discharging of shaft sleeve parts, there are still some technical defects:

[0003] Traditional mechanical hands usually use rigid clamps to clamp workpieces from above. When the clamping force is insufficient, the workpiece is easy to fall off during transmission. When the clamping force is too large or the positioning deviation is too large, it is easy to leave marks or scratches on the surface of the workpiece, especially for high-precision optical shaft workpieces, which has a great impact on the pass rate.

[0004] Cylindrical workpieces are easy to roll during conveying, including collision during feeding, which can easily cause large deviation, resulting in failure of centering with the grinding machine center, which needs to be adjusted repeatedly. Manual feeding also needs to adjust the angle of the workpiece to match the center of the center, which is time-consuming and labor-intensive. Moreover, the existing feeding mechanism is only suitable for some standard parts, and lacks effective orientation and limiting mechanism for cylindrical workpieces with large length-diameter ratio and easy rolling, resulting in unstable feeding.

[0005] During the machining process, long-time shutdown is required for waiting for material replacement, and the spindle of the grinding machine is in idle state for a long time. Although there are some automatic solutions, the feeding and discharging action and the processing time sequence cannot be deeply coordinated, the beat optimization is insufficient, the feeding and discharging stroke is long, and the waiting time of the grinding machine spindle is long.

[0006] At the same time, the independent feeding mechanical hand and the feeding and discharging movement guide rail of the mechanical hand have a long feeding and discharging stroke, which needs to occupy additional space around the equipment, making it difficult to deploy in a compact workshop environment.

[0007] In view of the above problems, the present application is developed through in-depth research. SUMMARY

DETAILED DESCRIPTION

[0055] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0056] Please refer to Figures 1-14 The present application provides a technical solution: a cylindrical workpiece outer circle grinding machine with active feeding and discharging functions, comprising a grinding machine frame 1 and an outer circle processing module 2, the outer circle processing module 2 comprising a grinding machine 21, a headstock center 22 and a tailstock center 23, the outer circle processing module 2 performing outer circle grinding on a cylindrical workpiece clamped between the headstock center 22 and the tailstock center 23 through the grinding machine 21. It also comprises a feeding assembly 3, a pushing assembly 4, a clamping jaw assembly 5 and a discharging assembly 6 installed in front of the outer circle processing module 2;

[0057] The feeding assembly 3 comprises an inclined feeding disc 31, which is inclined downward along the feeding direction and inclined to one side along the width direction, and the width direction inclined side is provided with a single-sided limiting plate 33; the downward inclination angle of the feeding disc 31 is 5°-15°, and the inclination angle to one side is 10°-20°. The lowermost end of the feeding disc 31 is provided with a feeding port 32, and the feeding disc 31 and the feeding port 32 are provided with a single-sided limiting plate 33 on the same side; the feeding assembly 3 is used for cylindrical workpiece feeding preparation and pre-storage, and the cylindrical workpiece is placed inclined to the horizontal direction in the feeding disc 31 while the feeding port 32 is inclined downward, and the single-sided limiting plate 33 is provided on one side, so that different lengths of cylindrical workpieces can be adapted and the side of the cylindrical workpiece is aligned for feeding under the weight.

[0058] The pushing assembly 4 pushes the jaw assembly 5 horizontally forward and backward through the pushing cylinder 41 below the feeding assembly 3; the jaw assembly 5 is used to cooperate with the pushing assembly 4 to clamp the workpiece through the jaw assembly 5 when the pushing assembly 4 moves to the feeding assembly 3, and then clamps the workpiece to the machining position between the two centers. The main body of the pushing assembly 4 includes a pushing frame 42, and the movable jaw 51 and the movable clamp block 54 are installed on the surface of the pushing frame 42, and the front end of the pushing frame 42 is limited by the lower end of the feeding port 32 when moving backward.

[0059] The jaw assembly 5 includes the movable jaw 51 and the movable clamp block 54 arranged forward and backward, and the movable jaw 51 and the movable clamp block 54 are connected by a clamping groove 55, and the maximum width of the clamping groove 55 is greater than the width of the feeding port 32. The suitable width of the clamping groove 55 and the feeding port 32 can also facilitate the cooperation of the feeding assembly 3 and the jaw assembly 5 to realize the transfer of the workpiece. The pushing cylinder 41 is connected to the movable clamp block 54, and the movable jaw 51 and the movable clamp block 54 are connected by a flexible cable 56 on one side of the upper end, and the flexible cable 56 is stretched to pick up the inclined cylindrical workpiece when the movable clamp block 54 moves backward, and the flexible cable 56 guides the workpiece to fall horizontally when the movable clamp block 54 moves forward;

[0060] The movable jaw 51 is movably installed on the front end of the pushing frame 42 through the movable shaft 52, and the torsional spring 53 is installed between the movable shaft 52 and the pushing frame 42, and the deflection angle of the movable jaw 51 is 0°-90°. The torsional spring 53 installed on the movable shaft 52 makes the movable jaw 51 have a deflection trend towards the movable clamp block 54, which facilitates the clamping of the workpiece by the movable jaw 51 and the movable clamp block 54, and the movable clamp block 54 can be turned outward by 90°, which facilitates the removal of the movable jaw 51 after the workpiece is fed into position and clamped for polishing.

[0061] The movable clamp block 54 is movably installed on the upper surface of the pushing frame 42 through the movable guide rail 58, and the elastic support 57 is installed between the rear end of the movable clamp block 54 and the rear end of the pushing frame 42, and the length of the elastic support 57 is equal to the activity stroke of the movable guide rail 58. The natural length of the elastic support 57 is equal to or slightly less than the activity stroke of the movable guide rail 58, which on the one hand does not affect the elastic support in cooperation with the movable jaw 51, and on the other hand, after the pushing frame 42 moves backward to the lower end of the feeding port 32, the movable clamp block 54 can move further backward to ensure that the clamping groove 55 is opened and the elastic cable 56 is stretched to facilitate the feeding.

[0062] The unloading assembly 6 and the pushing assembly 4 alternately move forward and backward to load and unload materials. The unloading assembly 6 includes a front unloading shovel 61 and a discharge plate 62, with the front unloading shovel 61 forming a telescopic structure at the front end of the discharge plate 62. The unloading assembly 6 is used to receive and deliver the ground cylindrical workpiece below the machining position between the two centers. A synchronous transmission wheel 43 is provided between the front unloading shovel 61 and the pushing frame 42. Both the upper side surface of the front unloading shovel 61 and the lower side surface of the pushing frame 42 are provided with meshing racks 45, and the outer ring of the synchronous transmission wheel 43 is provided with meshing tooth grooves 44. The meshing racks 45 and the meshing tooth grooves 44 form a meshing transmission structure. This causes the backward / forward movement of the movable clamping block 54 to drive the forward / retracting action of the front unloading shovel 61, realizing synchronous alternating unloading and loading operations.

[0063] The loading and unloading steps include:

[0064] S1. Material preparation: Cut the cylindrical workpiece and place it at an angle on the loading tray 31. The cylindrical workpiece is tilted and aligned with the single-sided limiting plate 33.

[0065] S2, Loading, pushing component 4 from... Figures 5-7 The normal working position shown is pulled to Figures 8-10 The loading and unloading stations shown are as follows: Figure 9 The tension cable 56 tilts to pick up the cylindrical workpiece, and then the push assembly 4 pushes the movable clamping block 54 forward, as shown. Figures 11-12 As shown, the elastic cable 56 resets, the cylindrical workpiece falls horizontally, and continues to move with the gripper assembly 5 as shown. Figures 13-14 As shown, it is pushed to the processing station;

[0066] S3. Grinding the outer diameter: The outer diameter machining module 2 clamps the cylindrical workpiece pushed in step S2 and grinds the outer diameter. The pushing component 4 then moves to the normal station.

[0067] S4. Unloading: Pushing component 4 is pulled from the normal station to the loading / unloading station again to load the material again. At the same time, unloading component 6 picks up the cylindrical workpiece after grinding the outer circle obtained in S3.

[0068] S5. Quality inspection and warehousing: The cylindrical workpieces obtained in S4 are inspected and put into storage.

[0069] Regarding the inclined loading mechanism for cylindrical workpieces: During operation, the cylindrical workpiece is cut and placed inclined on the loading tray 31. Due to the special inclined design of the loading tray 31, the cylindrical workpiece can automatically align itself with the single-sided limiting plate 33 and move towards the loading port 32. When the pushing component 4 is pulled from the normal station to the loading / unloading station, such as... Figure 8 As shown, the movable clamping block 54 moves backward, stretching the elastic cable 56, which increases the clamping groove 55 between the movable jaw 51 and the movable clamping block 54. One side of the cylindrical workpiece falls into the clamping groove 55 first, and the stretched elastic cable 56 then supports the other side of the falling cylindrical workpiece as follows:Figure 9 The buffer support is shown to tilt the cylindrical workpiece. Then, the push assembly 4 pushes the movable clamp block 54 forward, as shown in Figure 11 The elastic cable 56 resets the bending, and the workpiece gradually rotates to the horizontal state under its own weight, avoiding positioning deviation caused by instantaneous falling. Then, the movable clamp jaw 51 and the movable clamp block 54 clamp the cylindrical workpiece, and continue to push to the machining station with the clamp jaw assembly 5, as shown in Figure 14

[0070] The timing coordination principle of the loading and unloading actions is as follows:

[0071] As shown in Figure 10 and Figure 14 Before unloading, the front shovel 61 is mechanically linked with the movable clamp block 54 through the synchronous transmission wheel 43:

[0072] The movable clamp block 54 moves backward to load → the synchronous transmission wheel 43 rotates clockwise → the front shovel 61 extends to load;

[0073] The movable clamp block 54 moves forward to feed → the synchronous transmission wheel 43 rotates counterclockwise → the front shovel 61 retracts to avoid;

[0074] The loading and unloading actions are precisely timed and coordinated under a single power source.

[0075] The embodiment can effectively avoid workpiece surface indentation, improve yield, orient workpiece delivery, have good compatibility for workpieces of different lengths, improve equipment utilization, increase production capacity, reduce floor space, avoid external mechanical hand interference with the machining area, and realize full-process unmanned and efficient operation of cylindrical workpiece grinding under the premise of ensuring workpiece surface quality, thereby providing key technical support for automatic manufacturing of shafts and other cylindrical parts.

[0076] The contents not described in detail in the specification belong to the prior art known to those skilled in the art. Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, replacements and variations of the embodiments can be made without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.​
